Which of the following assumption violation cannot occur in the simple regression?
a. heteroscedasticity
b. autocorrelation
c. non-normality of error
d. serious multicollinearity

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
